Summary: This study presents a stable and dendrite-free potassium metal battery (PMB) with a cathode composed of Na+ and K+ co-intercalated vanadate (NKVO) and a liquid NaK alloy anode. The MXene-derived Na+-pillared NKVO exhibits improved specific capacities, rate performance, and cycle stability compared to the Na+-free counterpart. The study also demonstrates that thermally-treated carbon paper allows high surface tension liquid NaK alloy to adhere readily, enabling dendrite-free metal anodes. By clarifying the role of foreign intercalating cations, this study may lead to a more rational design of stable and high-performance electrode materials.

Summary: The demand for safe and renewable energy storage systems has led to the resurgence of aqueous zinc-metal batteries. However, the limitations of low Coulombic efficiency and short cycle life due to side reactions and zinc dendrite growth hinder the commercial development of these batteries. In this study, a ZnF2-rich interfacial layer derived from Ti3C2Tx MXene is prepared to address these issues. The results demonstrate that this layer redistributes Zn-ion flux, suppresses side reactions, and improves Zn-ion transfer kinetics. The Zn@MXene anode exhibits long cycle life and dendrite-free Zn deposition even at high current densities, showing potential for high-power rechargeable aqueous Zn-ion batteries.

Summary: Coating polymer on the surface is an effective way to enhance the stability of metal anodes in batteries. This study proposes a Ti3C2Tx MXene-assisted approach to construct polymer coating on zinc metal surfaces directly from the aqueous solution of monomers. By combining a doctor-blading method with spontaneous polymerization of monomers on the substrates at room temperature, a uniform, adhesive, and versatile coating layer assisted by a small amount of MXene is produced in one step. The coated zinc anode exhibits a long cycling lifespan and the assembled full cells show excellent cycling stability.

Summary: In this study, an ion-released MgI2-doped polyacrylonitrile (PAN) based nanofiber separator was designed to improve the solid electrolyte interphase (SEI) layer and suppress the formation of Li dendrites in lithium metal batteries. The combination of lithophilic MgI2 nanoparticles and polarized PAN matrix formed a high-compatibility interpenetrating network, enabling homogeneous ion transportation and dendrite growth suppression. The introduction of high-ion-conductivity LiI into the SEI layer through released I ions promoted the formation of a favorable and protective interface layer, leading to enhanced performance in lithium metal batteries.

Summary: The research team has developed an electrochemically inert and catalytic sp2c-COF separator to stabilize Li plating/stripping and accommodate high mass loadings of cathode in future high energy-density rechargeable batteries with Li metal anodes (LMAs). The nano-pores of sp2c-COF enable homogeneous Li+ flux and its electrochemical inertness prevents side reactions. The cyano-groups on sp2c-COF are critical for generating an inorganic-rich solid electrolyte interphase. Li symmetrical cells demonstrate excellent Li plating/stripping behaviors, and full batteries assembled with LiCoO2 and LiNi0.8Co0.1Mn0.1O2 cathodes show impressive areal capacities. This work provides an important strategy for the stabilization of LMA in rechargeable batteries.
